Logic Pro 7.2.1 update query

My son uses Logic Pro 7 music software and after trying to do an update to 7.2.1, there is a Note saying:
"Use of Logic Pro 7.2.1 with the Logic Node application, requires an update of the Node Software on your Node Machines. The Logic Pro 7.2.1 Update places the updated Node application into Applications/Utilities folder. Please copy it to the node machines and run it."
